通过对所取板结料试样进行化学成分检测、红外光谱分析、XRD分析、Factsage分析、SEM分析及EDS分析，研究了板结料形成的微观机理。研究结果表明：（1）板结料主要成分为MgO和C，且C不是直接来源于碳材，而是由料面发生的化学反应带来的；（2）料层表面发生了气-气化学反应，并生成固体MgO和固体C微粒，固体MgO呈针状并不断积聚成固体絮凝物，固体C微粒由于颗粒间发生团聚作用呈条状；（3）MgO固体絮凝物和条形固体C不断交织连接后形成了板结料颗粒并在后期经过板结过程形成块矿板结料。

The micro-mechanism of the hardened material formation was studied by using several measures, such as chemical composition test, FT-IR spectra analysis, XRD analysis, Factsage analysis, SEM and EDS analysis. The results can be shown as follows: (1) The main composition of hardened material was MgO and C, and C derived from a reaction taken place in material layer surface other than from the raw material injected into HCCF (Hermetic Calcium Carbide Furnace); (2) The solid MgO and the solid C formed when gas-gas reaction happened, the solid MgO was shaped as nee-dle at first and became flocculation with accumulation, and the solid C was in a strip shape by agglomeration between the solid C particles; (3) The hardened material particles formed when solid MgO flocculation and solid strip C mixed and connected together, and afterward the block hardened material generated through the hardening process.
